BOTTLE-CLOSURE.

Specification of Letters Patent.

Patented Feb. 11, 1919.

Application filed May 17, 1918. Serial No. 235,097.

To all whom it may concern:

Be it known that I, GEORGE Gr. DAVIS, a citizen of 'the United States,residing at Burke, in the county of Shoshone and State of Idaho, haveinvented certain new and useful Improvements in Bottle-Closures; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to improvements in bottle closures, especiallyadapted for attachment to milk bottles.

An important object of this invention is to provide a bottle closure ofthe character described adapted for insertion within the neck of thebottle for a substantial distance, thus preventing the milk when beingdispensed from the bottle, from coming in contact with the lip of thebottle.

' A further object of the invention is to provide a bottle closure ofthe character described, which is provided with a pivoted cover, whichis normally closed, and provided with means for quickly and convenientlyopening the same.

A further object .of the invention is to provide a bottle closure of thecharacter described which is neat in appearance, of highly simplifiedconstruction, convenient in use and cheap to manufacture. a

A further object of the inventionjis t provide a bottle closure, whichby virtue of its extreme simplicity of construction and cheapness ofmanufacture, will successfully compete with numerous other devices in ahighly crowded art.

Other objects and advantages of the mvention will be apparent during thecourse of the following description.

In the accompanying drawings forming a part of this specification and inwhich l ke numerals are employed to designate like parts throughout thesame,

Figure 1 is a vertlcal central sectional view through my improved bottleclosure, showing the same applied to a bottle,

Fig-2 is a plan view of my improved bottle closure,. e

Fig. 3 is a plan view of the same, the uvoted top thereof being removed,and,

Fig. 4 is a rear elevation of the closure, showing the o eratin lever.

In the drawlngs, w erem for the purpose of illustration is shown thepreferred embodiment of my invention, the numeral 5 designates a milkbottle having the usual bead 6 arranged outwardly of an annular recesswithin the neck of the bottle, forming an annular shoulder 7. Myimproved bottle closure comprises a cylindrical member 8 adapted to bearranged within the neck of the bottle and provided with a longitudinalslot 9. In the manufacture of the closure, the cylindrical member 8 willhave its circumference. slightly greater than the inte rior of the neckof the bottle, thus in inserting the device in the neck of the bottlethe diameter of the member 8 will be lessened by the presence of theslot 9. An annular shoulder 11 formed on the upper end of thecylindrical member or collar .8 carries a flange 12, said flange beingsubstantially L-shaped in cross section and extending over the top ofthe bead 6. An annular washer or gasket 13 is interposed between theannular shoulder and the annular shoulder 11 for the purpose ofeffecting a liquid tight oint.

Formed integral with the annular flange 12 and extending over a portionof the opening in the collar 8 is a plate 14 carrying alining sleeves15. A cap 16 extending over the opening in the bottle is provided withalining sleeves 17 along its straight edge. As shown in Fig. 2, thesleeves 15 and 17 are adapted to be arranged in longitudinal alinementfor the reception of a pivot 18 extending therethrough. An operatinglever 19 is secured to the cap 16, as at 20, by

solder or any other suitable means. As shown in Fig. 1, the lever 19 isprovided with a slight transverse curve 21 near the upper end thereof topermit of a coil spring 22 being arranged on the pivot ISbetWeen thesleeves 15. One end 23 of the coil spring 22 contacts with theinnerportion of the lever 19, while the other end of the coil spring 22contacts with the plate 14. It is thus apparent that this specificspring arrangement adds greatly to the utility and appearance of theclosure, since the milk at no time contacts with the spring, which isapt to collect dirt, and it is excluded from view thus adding totheneatness of the closure. As shown in Fig. 1, the lever 19 is bent toconform to the shape of the bottle when the cap is in an open position.

In applying my improved bottle cap to the neck of a bottle, it isapparent that the cylindrical member 8 is pressed within the neck of thebottle and the device is immediately ready for use. It Will be notedthat in dispensing the milk, it at no time comes in contact with the lipof the bottle which has been previously exposed and free to collect,dirt, dust, germs, and so forth..

Having thus described my invention, What I claim is:

1. A bottle cap comprising, a cylindrical member adapted to extend intothe neck of a bottle; an annular'shoulder formed on one end of thecylindrical member; an annular flange extending from the annularshoulder, said annular flange being L-shaped in cross section andadapted to extend over the lip of the bottle; a plate extending over aportion of the opening in the bottle; a cap pivotally secured to theplate, a lever attached to the cap and extending over the side of thebottle; and a spring arranged between the leverand said plate andadapted to normally hold the cap closed.

2. A bottle cap comprising a, cylindrical member adapted to be arrangedin the neck of a bottle; an annular flange extending from saidcylindrical member and extending over the lip of the bottle, saidannular flange being L-shaped in cross section, a plate formed integralWith said annular flange and extending over a portion of the opening inthe bottle; spaced alining sleeves formed on the plate and adjacent oneedge thereof; a cap arranged over the opening in the bottle; spacedalining sleeves formed along one edge of said cap and adapted to alineWith the sleeves of said plate; a pin adapted to extend through thesleeves of said cap and said plate to permit of the cap partaking of a.pivotal movement; a lever attached to the cap and extending over theside of the 40 bottle; and a coil spring arranged on said pin betweenthe spaced sleeves of said plate and having its ends engaging the plateand said lever, said spring being adapted to normally hold the capclosed. 7 5

3. A bottle cap comprising a cylindrical member adapted to extend intothe neck of a bottle; an annular shoulder formed on one end of thecylindrical member; an annular flange extending from the annularshoulder, said annular flange being L-shaped in crosssection and adaptedto extend over the lip of the bottle; a plate extending over a portionof the opening in the bottle and having one edge thereof straight; a capadapted to be arranged over the remaining opening in the bottle andhaving one edge straight, said straight edge being adapted to bearranged parallel to the straight edge of said plate; alining sleevescarried by the straight edges of said cap and said plate; a pinextending through the alining sleeves; a lever secured to the cap andextending over the side of the bottle; and a coil spring arranged on thepin and disposed between the lever and said plate and adapted tonormally hold the cap closed.

In testimony whereof I afiix my signature in presence of tWo Witnesses.
